Respected Members, I am working on the behaviour of hydrogen at the Cu/Ni (111)-graphene interface. In case of Ni (111), the atomic H on the interface diffuse inside the the surface. While in case of Cu (111), the H atom stays at the Cu(111)-graphene interface. It seems that H atom experiences more electrostatic repulsion from the graphene in case of Ni (111). Kindly suggest how can I quantify electrostatic repulsion in both cases ?
